Vin Diesel stars as the last witch hunter in a movie that has precious little to do with hunting witches. The film plays out like a refugee from the year 2005; it's precisely the kind of CG-filled and PG-13 supernatural actioner that would have been at home in megaplexes alongside "Constantine" and "I, Robot." Today it just feels curiously antiseptic and out of touch, unable to coast on Diesel's charm alone.
